Exercise 15 Page 279

To describe the pattern of the sequence, we need to find the change that occurs between each pair of consecutive terms. Here, notice that the difference between each pair of consecutive terms in the sequence is 1.1. We can describe the pattern as add 1.1 to the previous term. 1.1+ 1.1 ⟶2.2+ 1.1 ⟶3.3+ 1.1 ⟶4.4+ 1.1 ⟶ ... To find the fifth and sixth terms, we follow this pattern. 1.1+ 1.1 ⟶2.2+ 1.1 ⟶3.3+ 1.1 ⟶4.4+ 1.1 ⟶ 5.5+ 1.1 ⟶ 6.6
